Belfast-born actor Kenneth Branagh features in the thrilling trailer for Christopher Nolan's war film Dunkirk.

The Dark Knight and Interstellar director's latest project focuses on Operation Dynamo, the evacuation in which over 300,000 Allied soldiers were rescued from Dunkirk’s harbour and beaches in 1940 after German forces invaded the country.

From the look of the trailer, the film appears to be a dramatic departure from Nolan's most recent projects, the mind-bending sci-fi epics Inception and Interstellar.

However, with breathtaking visuals and a typically heart-stopping score from composer Hans Zimmer, Dunkirk looks as though it will be another impressive audition to Nolan's filmography - and is set to be one of next summer's most eagerly-anticipated releases.

Dunkirk will be released in UK cinemas on July 21. Watch the trailer below!
